3. Review the basic theorem of plane vectors: if e1 and e2 are two non-collinear vectors in the same plane, then for any vector a in this plane, there is and only one pair of real numbers Î»1, Î»2 such that a = Î»1 e1 + Î»2 e2. Two non-collinear vectors e1, e2 are called a set of bases of all vectors in this plane.
